To enter cheats in Saints Row IV, press BACK if you are playing on Xbox 360 or press SELECT if you are playing on PlayStation 3. Go to "Extras", and your options will be Cheats or Stats. Click on cheats and then input any of the cheats.

Having cheats enabled will disable your ability to earn achievements and it will also turn off the auto-save functionality.

This is cumulative, so you don't actually have to do all of this sprinting at once. That being said, it will obviously make this achievement a lot easier if you have all the sprint upgrades. This will probably come naturally just from playing the game, however, so don't worry about spamming it until after you've already been through all of the missions.

Customized the style of all the weapons on your radial and hit the Simulation with style.

Customize the weapons on your radial menu by going to a store and choosing to customize them. The customizations are all free, just choose the different skins for any of the different weapons that you currently own.

The Fire Buff is unlocked by playing the main story missions. Activate it by first equipping it with the d-pad and then pressing RB. This will make yourself light on fire and also make all your bullets be of the flaming variety.

This will probably be unlocked just by naturally playing the game. However, if you don't have this one after completing all the missions, just go to the top of a really tall building, hold A, and then jump off the building. The fall will count as part of the Super Jump. Just keep repeating this and eventually this will unlock.

This requires that you kill Aliens with the weapons, so it's a bit annoying that the game doesn't specify that requirement. The "best toys" refer to the alien weaponry obtained throughout the game. Completing the missions will unlock all of the alien weapons for you.

Created and shared a character online, you're a part of the Saints Row community now!

You can't download any characters without the Online Pass, but you can get this achievement without it. After making your character, you will be given the option to upload that character to the Saints Row servers. If you don't have a Saints Row account, it will first ask you to make one, however.

This achievement description is incredibly vague. To get it, you need to play for at least 2 hours as a male and at least 2 hours as a female. Just start a new save as the opposite sex than before and play for 2 hours to get this one (assuming you've already played 2 hours with your main).

At one point in the game, you will be asked to choose between a blue door and a red door. The blue door means you continue your quest, whereas the red door means that you kill yourself in exchange for Zinyak freeing all the humans he has on his ship.

Choosing the red door results in a game over, but it is necessary to get this achievement.

The Wardens are the beefier aliens that you encounter at numerous points in the game. They are first encountered through the main story missions, and can then be found and fought elsewhere in the simulation.

Input these cheat codes to spawn the different vehicles. The vehicle is listed on the left, and the word to the right, starting with "give" and separated from the vehicle name by a hyphen, is what you will type into the cheat code menu. For the most part, all you have to do is type "give" and then the name of the vehicle with no spaces.
